Specification of Letters Patent.

I'atented March 5, 1907.

Application filed May 11, 1905. Serial No. 259,914.

T at whom it may concern:

Be it known. that I, Gnonen WILLIAM PARK, a citizen-of the United States, and a resident of Denver, in the city and county of, Denver and State of Colorado, have invented a new and improved Eraser, of which the following is a full, clear, and exact description.

This invention-relates to erasers; and it I consists, substantially, in the details of construction and combinations of parts hereinafter more particularly described, and pointed out in the claims. 4

One of the principal objects of the invention is to provide an eraser combined with or I forming a part of the tubular member ordinarily employed. with fountain-pens for protecting the pen or writing-point thereof; I

, tive of the eraser detached.

A further-object is to provide an eraser I '(thus associated with a fountain-pen) which is simple in construction and comparatively i inexpensive to manufacture, besides being thoroughly effective and reliable for its pur l poses and possessing the capacity for long and repeated service.

The above and additional objects are attained by means substantially such as are. l illustrated in the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a fountain-pen provided with the ordinary tubular member for protecting the pen or writing-point thereof. Fig. 2 is a part-sectional view of an eraser embodying myimprovements and showing the same as combined with or forming a part of the ordinary tubular protect-- ing member for the pen or writing-point of a fountain-pen, and Fig. 3 is a view in perspec- Before proceeding with a more detailed description it may be stated that in the forms of my improvements herein shown I employ an ordinary fountain-pen having a tubular protector for the writing-point thereof special construction, associated-or combined with which is a detachable eraser of special construction.

Reference being bad to the accompanying drawings by the designating characters marked thereon, 1 represents an ordinary fountain-pen provided at 2 with a member for protecting the writing-point 2 thereof when the pen is carried in the pocket, said away, it may be readil member in the present instance being provided with a detachable cap or closure 3 therefor.

As shown in Fig. 2, the cap or closure 3 is internally threaded at the open end thereof to screw upon a corresponding threaded projection 4, formed integral with the upper end of the said member'2 and reduced in external diameter, as shown, said projection 4 being also internally threaded at 5.to engage a corresponding thread 6, formed externally with a plug 7, which is provided with recesses in its ends, as shown at 8, and has in serted in one recess a block 9 of rubber, either for pencil or ink erasures, the shank of a knife-eraser 10 being sccuredin the recess in the other end of the said plug, the knifeeraser extending diametrically across the same with a knife-eraser 10 and ta ered to a point, as shown, and formed on eac side thereof at 11 with an erasing or cutting edge. It will thus be seen that when my improved eraser is notin use the cap or closure 3 may be applied to themember 2 flush therewith, so that not only will the pen-point 2 be protected when the same'is inserted within the member 2, but the eraser will also be protected from injury and prevented from being lost or misplaced, as is apparent.

may be conveniently assoc ated with a fountain-pen and carried in the pocket with the latter to be always availablefor use when required, and it is thought the advantages of my improvements will be apparent.

In making use of the invention it is necessary to unscrew or slip off the cap or closure 3 to enable simply the rubber eraser 9 to be used in the ordinary way; but whenever it is desired to use the knife-eraser 8 the plug or cap 6 is unscrewedfrom its connection with the threaded projection 4 of the member 2, whereupon either edge of the said knife-eraser may be employed in the ordinary way by simply grasping'the plug 6 between the fingers and thumb of the hand. After use the device may be again inserted Within the member 2, as closure 3 applied.

Whenever the plug mp y 9 has become worn replaced, of course, and so, too, may the 'fe-eraser of either form herein shownbe replaced by another when it has become wornor otherwise unfit for use.

before, and the cap or' open at Having thus described my invention, 1 claim as new and desire to secure by Letters Patent Y I 1. A rotecting-cover .for V a fountain-pen 0th ends and having one end externally and internally screwthreaded,' said cover having an internally-screw-threaded cap screw'in on the said cover, an externally? screwhrea ed plug screwing into the cover and having a recess in each end, said lug be-- ing of even diameter throughout an having of even diameter throughout and having its screw-thread extending the length thereof, a

block of rubber in one recess of the lug, anda blade tapering to a point and aving ashank fitting in the other recess of the said plug, the base of the blade being'of a width 3. As a new article of manufacture a protecting-cover for a fountain-pen, 'compris' an open-ended shell having one'end reduce andinternally screw-threaded at said reduced end, a removable cap fitting on the rea proximately equal to the diameter of the duced end of the shell, and an exteriorlyscrew-threaded plug screwing into the shell and providedxwith-a block of rubber in one end and a blade in the other end.

in testimony whereof I have signed my name to this specification in the presence of two subscribing Witnessesf GEORGE WILLIAM PARK.
